  1. NDIIPP and NGDA National Preservation Network For Digital Content

  2. NDIIPPNational Digital Information Infrastructure and Preservation ProgramLibrary of Congress (LOC)

  3. Library Of Congress Lead Institutions Partnerships • UC Santa Barbara: Geospatial Data • California Digital Library: Web political content • WNET/PBS: Educational television • Emory University: Southern digital culture • NC State University: Geospatial data • U of Maryland: Dot.com business records • U of Michigan: Social science data • U of Illinois: State government publications

  4. Goals for the LOC Partnerships • Identify/select/collect content; communicate strategies for doing so • Probe intellectual property issues • Collaborate broadly in developing a shared technical architecture • Study economic sustainability • Identify and share best practices • Learn how to build and incrementally improve a preservation network

  5. DL Evolution at UCSB09-2006 Leveraging existing infrastructure • 1986 to 1994 External design (Keck) • 1994 to 2000 ADL development (NSF) • 2000 to 2004 ADL operational (UCSB) • 2004 to 2010 Archiving via NGDA (LOC) • 2006 Move towards research data repository (UCSB, U. of Tenn., LOC) • Current DL infrastructure at Davidson • High speed Internet 2 networks • 50 Terabytes of data storage • 160 TB’s of tape backup • 10 years of DL expertise • Archive software infrastructure • Moving towards federated query of distributed content

  6. Spatial Organizing Concept • Searching for a data object, usingan “earth” location, adds a powerful search dimension to traditional library cataloging methods. • Spatial coordinates are a universal language. During searching, this search method overcomes any cultural or language anomalies that occur in catalog records. • Data organization, whether terrestrial, planetary, or the human body via coordinate systems, guarantees a “completeness” of search results. • “I want all available information about this location”

  7. Art about … Botanical Survey Earth Science Data Museum Artifacts What is GeoSpatial Data? • Information Associated With a Location • It may be • Any Format • Any Language • Any Culture • Any Subject • Examples • Books About… • Maps or Cartographic Datasets • Photography - Imagery • Report or Surveys About… • Statistical • Science and Research About .. Text-Field Guides

  8. Goals of the NGDA Project • Create federated robust preservation environments • Save at-risk digital data for future users • Construct shared collection development policy • Build a geospatial format registry • Develop best practices for geospatial preservation • Develop guidelines for participation in a federated archival network • Deploy a three node implementation

  9. Technical Architecture-UCSB access ingest Web ADL OAI export bulk loader archival system storage subsystem standard, public data model databases, caches, etc.

  12. Current Operational Digital Libraries Over 20,000,000 searchable records • Alexandria Digital Library • The ADL Gazetteer • NGDA • SPOT Imagery Archive (soon) • Cylinders Collection (Edison Recordings) • California Ethnic & Multicultural Archives • Others

  13. In development • LOC extension of partnership funding through 2010 • NGDA deploying and testing federated architecture (Stanford, LOC and UCSB) • SPOT Image Catalog and Repository • Adapting existing architecture to UCSB academic digital library • Exploring software such as Greenstone, Fedora, and D-space for applicability of services and tools

  14. Description of NGDA’s Web Data Browser(Beta)

  15. Figure 1. Upon loading the NGDA collection browser Landsat imagery over the US is loaded by default

  16. Figure 2. After switching to the DRG historical map collection, a orange "cluster button" indicates that there are a number of maps of California available to view at a higher zoom level. Pressing the cluster button recenters the map and redisplays the atlas at higher resolution.

  17. Figure 3. The same collection at a higher zoom level. The maps are still too small to view at this distance, but we have more detailed information regarding the range of the collection (e.g., more maps over central and southern California than over the Nevada California border).

  18. Figure 4. At a higher zoom level we can see the DRG maps aligned geospatially and tiled over Santa Barbara.

  19. Figure 5. After two browse panels have been opened for more detailed inspection/comparison. Once a browse panel is opened, a user may download (if permitted) the larger full-resolution map image and project data, or choose to see the full detail of the catalog records for a particular item.

  20. Figure 6. Overlapping geospatially aligned historical air-photography over Santa Barbara taken from a single flight in the 1940s.

  21. Figure 7. Browse panel opened of DOQQ air photography over California for downloading.

  22. Figure 8. Multiple browse panels opened of Landsat imagery over the Middle East.
